The apicobasal dispersion of ventricular repolarization in humans is associated with age and affects arrhythmia vulnerability

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated the age‐ and sex‐related differences in the apicobasal repolarization gradient (ABRG) and evaluated their possible role inventricular arrhythmia vulnerability. Electrocardiographic imaging (ECGI) was performed in healthy subjects during sinus rhythm, and the average recovery time (RT) and activation–recovery ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Multifactorial QT Interval Prolongation and Takotsubo Cardiomyopathy

Case Reports in Cardiology, 2014
A 71-year-old woman collapsed while working as a grocery store cashier. CPR was performed and an AED revealed torsades de pointes (TdP). She was subsequently defibrillated resulting in restoration of sinus rhythm with a QTc interval of 544 msec.

Inhibition of Nonsense-Mediated mRNA Decay by Antisense Morpholino Oligonucleotides Restores Functional Expression of hERG Nonsense and Frameshift Mutations in Long-QT Syndrome

, 2010
Mutations in the human ether-a-go-go-related gene (hERG) cause long-QT syndrome type 2 (LQT2). We previously described a homozygous LQT2 nonsense mutation Q1070X in which the mutant mRNA is degraded by nonsense-mediated mRNA decay (NMD) leading to a ...

The effects of age and ganglioside composition on the rate of motor nerve terminal regeneration following antibody-mediated injury in mice [PDF]

, 2013
Gangliosides are glycosphingolipids highly enriched in neural plasma membranes, where they mediate a diverse range of functions and can act as targets for auto-antibodies present in human immune-mediated neuropathy sera.

High‐Sensitivity Cardiac Troponin T in Healthy Sport‐Participating Youth Aged 8–16 Years: Reference Values From the Cor‐School Cohort

American Journal of Human Biology, Volume 37, Issue 12, December 2025.
ABSTRACT Objectives High‐sensitivity cardiac troponin T (hs‐cTnT) is widely used in adult cardiology, yet pediatric reference values remain scarce. This study aimed to establish reference values for hs‐cTnT in healthy sport‐participating youth aged 8–16 years from Spain; to examine differences by age, sex, and pubertal stage; and to explore ...

Genotype-Phenotype Relationships in Long QT Syndrome : Role of Mental Stress, Adrenergic Activity and a Common KCNH2 Polymorphism [PDF]

, 2006
Long QT syndrome is a congenital or acquired arrhythmic disorder which manifests as a prolonged QT-interval on the electrocardiogram and as a tendency to develop ventricular arrhythmias which can lead to sudden death.

Sudden unexpected death in epilepsy genetics: Molecular diagnostics and prevention. [PDF]

, 2016
Epidemiologic studies clearly document the public health burden of sudden unexpected death in epilepsy (SUDEP). Clinical and experimental studies have uncovered dynamic cardiorespiratory dysfunction, both interictally and at the time of sudden death due ...
